摘要： A video processing method includes: receiving an omnidirectional content corresponding to a sphere, obtaining projection faces from the omnidirectional content, and creating a projection-based frame by generating at least one padding region and packing the projection faces and said at least one padding region in a 360 VR projection layout. The projection faces packed in the 360 VR projection layout include a first projection face and a second projection face, where there is an image content discontinuity edge between the first projection face and the second projection face if the first projection face connects with the second projection face. The at least one padding region packed in the 360 VR projection layout includes a first padding region, where the first padding region connects with the first projection face and the second projection face for isolating the first projection face from the second projection face in the 360 VR projection layout.

摘要： In order to overcome the issue caused by a decoded block vector (BV) pointing to a reference block overlapping with an unavailable area, various methods are disclosed. According to one method, if the reference block overlaps with an unavailable area, the reference pixels in the unavailable area are generated for IntraBC prediction of the current block by padding from neighbouring available pixels. The padding can be done in the horizontal direction and then the vertical direction. The padding may also done in the vertical direction first and then horizontal direction. In another method, if the reference block overlaps with an unavailable area, the reference pixels in the unavailable area are generated for IntraBC prediction of the current block by using previous decoded pixels in the unavailable area. A pre-defined value may also be used for the unavailable area.

摘要： When performing an inter predictive encoding on any image frame x is required, a reference image frame is determined for image x; image x is a P-frame image or a B-frame image; for each reference image frame, following processes are respectively performed: whether resolution of a reference image frame is the same as resolution of image x is determined; if resolution of the reference image frame is different from resolution of image x, resolution of reference image frame is adjusted to be the same as resolution of image x; if resolution of each reference image frame is the same as resolution of image x, inter predictive encoding is performed on image x based on each reference image frame.

摘要： A moving image encoding apparatus executes moving image encoding of a syntax element relating to a moving image signal VS to form an encoded bitstream CVBS. Padding processing of adding padding processing data PD to the moving image signal VS is executed prior to the moving image encoding, and the horizontal and vertical sizes of an additional moving image signal added the padding processing data are set to an integral multiple of an encoded block size in the moving image encoding. It is determined that the encoded block of the syntax element belongs to which of the moving image signal VS and the padding processing data PD. In a case where the encoded block belongs to the former, an encoded bitstream having a large code amount is formed. In a case where the encoded block belongs to the latter, an encoded bitstream having a small code amount is formed.

摘要： A video coder may determine a search region for coding a current block of video data using Intra Block Copy (Intra BC). In some examples, the video coder determines a central point for the search region, and determines the search region for the current block based on the central point and a defined size for the search region. The video coder stores reconstructed blocks of the video data from a current picture that includes the current block in a memory based on the determined search region. The video coder codes information from which to identify one of the reconstructed blocks within the search region, and codes the current block based on the identified one of the reconstructed blocks according to Intra BC.
